Caecal volvulus is the axial twist of the caecum, ascending colon and terminal ileum around the mesenteric pedicle. This infrequently encountered clinical entity is responsible for 1-1.5% of all intestinal obstruction with a mortality of 10-40% depending on the presence of colon viability or intestinal gangrene. Many factors have been referred as correlated to caecal volvulus development, mainly anatomical predisposition and previous abdominal operations. Pre-operative diagnosis plays an important role in the management of such patients. Unfortunately, clinical signs, symptoms and laboratory tests are never specific enough to lead to a prompt diagnosis. Abdominal radiography and computed tomography may allow a diagnosis if typical signs are present. However, up to 30% of patients do not show these radiographic peculiarities, making the diagnosis difficult or impossible. Moreover, the low incidence of this disease is often responsible of a wrong or imprecise diagnosis, especially for radiologists who work with low volume of patients. We report a case of a patient with caecal volvulus, in which laparotomy was unavoidable to reach a diagnosis.
